If you filed your 2024 taxes in January or February and already received your refund, you might think the chapter is closed. But here in Houston, where the energy sector fluctuates, real estate markets shift, and small businesses face unique challenges, the initial return you submitted is rarely the final word. In fact, the IRS Data Book shows that over 3.5 million amended returns were processed in fiscal year 2023, with taxpayers receiving an average additional refund of $1,800. If you missed a deduction for your home office in The Heights, forgot to report a 1099 from a side gig in Katy, or simply didn’t know about the Texas franchise tax credit, an amended return could put hundreds—or thousands—of dollars back in your pocket. At Big Ass Tax Returns in Houston, we handle amended returns every single week, and we want you to understand exactly how the process works so you can stop leaving money on the table.
An amended return is simply a corrected version of your original tax filing. You use IRS Form 1040-X to update your income, deductions, credits, or filing status. The most common reasons to amend include discovering you forgot to claim the Child Tax Credit, realizing you missed a charitable deduction, or learning that you incorrectly reported capital gains from a property sale in Cypress. But here’s the critical detail: you cannot e-file an amended return. It must be mailed to the IRS, which means the process takes longer—typically 16 to 20 weeks for processing, though the IRS has been running slightly ahead of schedule in 2024. If you owe additional tax, you should file the amendment as soon as possible to stop interest and penalties. If you are due a refund, you generally have three years from the original filing deadline to claim it. That means for 2021 returns, the window closes on April 15, 2025. Do not let that deadline slip.
One of the biggest fears we hear from Houston clients is that filing an amendment triggers an audit. That is a myth. The IRS processes millions of amendments routinely, and filing one does not increase your audit risk. In fact, the IRS expects corrections—it’s baked into the system. What does raise a red flag is a large, unexplained change in income or deductions. For example, if you originally reported $50,000 in income but amend to $150,000, the IRS will want to know why. But if you simply add a $2,500 educator expense deduction or correct a missed $1,000 charitable contribution, the risk is negligible. At Big Ass Tax Returns, we price amendment services starting at $150 for simple corrections (like adding a single deduction) and $350 for more complex returns involving business income or rental properties. Our average client sees an additional refund of $1,200 to $2,400. That is a strong return on a modest fee.
The process is straightforward but requires precision. First, gather your original tax return and the new documents that support the change. For example, if you are adding a home office deduction, you need a diagram of your workspace, utility bills, and a log of business use. If you are correcting a 1099-NEC from a freelance job you did for a company in the Energy Corridor, you need the corrected form from the payer. Next, complete Form 1040-X. This form has three columns: Column A shows the original figures, Column B shows the net change, and Column C shows the corrected totals. You must explain the reason for the change in Part III. For instance: “Taxpayer omitted Schedule C business income from freelance web design services. Corrected amount added.” Then, you mail the form to the IRS address for your region. For Houston residents, that is the Ogden, Utah service center. Do not attach the original return—only the 1040-X and any new schedules or forms. If you are due a refund, you can choose to have it direct deposited or mailed as a paper check. If you owe money, you can pay online via IRS Direct Pay or include a check with the amendment.
Many Houstonians forget that Texas does not have a state income tax, so no state amendment is needed. However, if you lived in another state during the tax year and filed a non-resident or part-year return, you may need to amend that state’s filing as well. For example, if you moved from California to Houston in July 2023 and filed a California part-year return, but later discovered you missed a deduction for moving expenses, you would need to file a California amended return. The process mirrors the federal one but uses the state’s equivalent form. At Big Ass Tax Returns, we handle multi-state amendments for $200 per state. It is a common scenario for oil and gas workers who rotate between Texas and Louisiana or Oklahoma.
The most frequent error we see is people trying to amend too quickly. If you filed your original return and it is still being processed, the IRS will reject your amendment. Wait until you receive your refund or a notice that the return has been accepted. Another mistake is forgetting to sign the form. The IRS will not process an unsigned 1040-X. Also, do not use the “married filing separately” status if you meant to file jointly—that changes your entire tax picture and requires a special election. Finally, if you are amending because you received a corrected W-2 or 1099 after you filed, double-check that the new form matches what you are reporting. A mismatch will trigger a CP2000 notice, which can delay your refund by months. Our team at Big Ass Tax Returns reviews every amendment for these exact issues before it goes in the mail.

Call (225) 396-5511The IRS currently processes Form 1040-X in about 16 to 20 weeks from the date they receive it. You can check the status using the “Where’s My Amended Return?” tool on the IRS website, which updates once every three weeks. If you file by mail, make sure you use a tracking service like certified mail so you have proof of delivery. At Big Ass Tax Returns, we recommend clients allow up to six months for the full process, though many see refunds in 12 to 14 weeks.
Absolutely. In fact, that is the most common scenario. You simply report the original refund amount in Column A of Form 1040-X, then show the corrected refund or balance due in Column C. If you are due more money, the IRS will send you a separate check for the difference. If you owe money, you will need to pay the additional tax plus any interest. The IRS calculates interest from the original filing due date, so it is best to file the amendment as soon as possible.
If the amendment is simple—like adding a single charitable deduction or correcting a Social Security number—you can handle it yourself using the free forms on IRS.gov. But if the change involves business income, rental properties, capital gains, or multi-state issues, a professional is strongly recommended. The IRS is less forgiving with amended returns because they are reviewed manually by a human agent. One error can delay your refund by months.
